FYI, I discovered that there are more types of Performance Package Sachs shocks, while just a type of springs.
Toyota used always the same shocks, that differ from Subaru. Subaru had 2 different shocks set, revised for models G and H (let's say from 2018).
Then there are the Toyota GR and Subaru STi, with specific springs, but this is another story...

That's actually very interesting. Do you have the specs for all the combinations for these?

I’m actually about to install Sach Dampers and STI pinks tomorrow. I was between rce yellows and STI pinks. Got a really good deal on very low mileage Sachs off a 2019 PP and STI pinks off a 2018 TS. Quick question, are the rear LCAs on the performance package different than the standard models? Or would I be able to just put these right in?

The rear LCA's are the same across the range as far as I'm aware. Also, the STI Pinks are not the same as the TS model springs, even though they are also pink. I have the TS springs and dampers also waiting to go on the car.

Thanks! Is there any information available on the TS STI pink springs? I’ve recently learned these are not your typical STI pinks. No intention of thread jacking and thank you all again. Timing of this thread couldn’t be any more perfect for me personally lol.

Are the Sachs monotube? I am aware that the standard shocks are a good compromise between performance and cost, but I am not sure about the ones from Sachs. Maybe a bit better than standard while keeping the cost relatively low?

Nope, still twin tubes. Better for street, worse for track.

Rear spring: SU003-07196 (Models E-F, same as non PP)
Rear spring: SU003-08065 (Models G-H, same as non PP)

Front strut R: SU003-06790 (Marked 20310-CA140 on strut, red sticker)

Rear spring EU/US: 20380CA211 (Models G-H from production date 20181001, same as non PP)
Rear spring JP: 20380CA200 (Models E, F, G production date 20180101-20180930, same as non PP)
Rear spring JP: 20380CA201 (Models G-H from production date 20181001, same as non PP)

Front strut R: 20310CA160 (Models E-F, blue sticker)
Front strut L: 20310CA170 (Models E-F, blue sticker)
Rear shock: 20365CA120 (Models E-F, blue sticker)

Front strut R: 20310CA280 (Models G-H, yellow sticker)
Front strut L: 20310CA290 (Models G-H, yellow sticker)
Rear shock: 20365CA240 (Models G-H, yellow sticker)

GR (10 mm lower):
Front spring: 48131-18060 (Made by Chuhatsu)
Rear spring : 48231-18030 (Made by Chuhatsu)

Front strut R: 48510-18040 (Yellow sticker)
Front strut L: 48520-18040 (Yellow sticker)
Rear shock: 48530-18050 (Yellow sticker)

STi/tS 2017+:
Front spring MT: 20330CA260 (Marked 1 light blue and 1 yellow)(Lowered 10 mm)

Front strut L: 20310CA310 (Models G-H, purple sticker)
Rear shock: 20365CA250 (Models G-H, purple sticker)


Update: reading a Japanese article, I discovered that Subaru added a couple of stabilyzing spoilers behind rear wheels, on the bumper in models G and H, and suspensions have been tuned accordingly. Toyota didn't, that's why Subaru rear shocks have been revised, but not Toyota's.


Update 2: not Sachs, but these are the other OEM specific options.

GRMN:
Front spring: 48131-18050
Rear spring : 48231-18020

Front strut R: 48510-18030
Front strut L: 48520-18030
Rear shock: 48530-18040


tS Model B (2013) (15 mm lower):
Front spring: ST20330AS010 (Marked 1 blue and 1 orange)
Rear spring : ST20380AS000 (Marked 1 white and 1 orange)

Front strut R: ST20310AS000
Front strut L: ST20310AS010
Rear shock: ST20365AS000


tS Model D (2015) (15 mm lower):
Front spring: ST20330AS030
Rear spring : ST20380AS000 (Marked 1 white and 1 orange)

STi Aftermarket spring kit (15 mm lower):
Front spring: ST20330AS000 (Marked 1 white and 1 orange)
Rear spring : ST20380AS000 (Marked 1 white and 1 orange)(same of tS Model B/D)


STi Aftermarket shocks+spring kit (15 mm lower):
Front spring: ST20330AS010 (Marked 1 blue and 1 orange)(same of tS Model B)
Rear spring : ST20380AS020 (Marked 1 blue and 1 orange)

Front strut L: ST20310AS050 (Made by Bilstein, inverted strut)
Rear shock: ST20365AS020 (Made by Bilstein)


86/BRZ Race coilover, STi and TRD are same kit (made by KYB):
TRD shocks kit MS260-18001 (Yellow color)
TRD springs kit MS250-18001

STi shocks kit 20300AS000 (Silver color)
STi springs kit 20300AS010


I missed the specific Toyota 86 14R60 coilover, as you can't order them, and not suitable for street, with square 14.6K springs!

Yes, in Japan they are identified as model number, let's say that model E Is built from April 2016, it's the first facelift.

And that just the Sachs dampers.. I wonder if the CA--- indicates the valving like how bilstein tags their shocks. There a different shock for every version of the sachs equipped cars it seems like.

CAxxx are just increment numbers of the same part. Not related with valving. Our cars were upgraded slightly year-by-year and suspension was improved from time to time too. There were numerous official communications about revised damping and a bit better comfort etc.

Looking at the part numbers used, its probably not. Would have been nice, and you can order a replacement shock based on the valving. Specially when there are so many options to pick from.

I'm currently running a set of 2015 Showas off a BRZ with 2013 BRZ front spring and my factory 2013 FRS rear spring. The ride using the 2015 was better, initially and for a good while. Now that I've some miles on the 2015 Showas, I dont think I can say the same.

I suppose you have to expect that. Oil eventually breaks down, and gas pressure will escape. Its just a matter of how long it maintains performance. It only goes one direction. Gas pressure and oil viscosity is not gonna magically increase with usage.
